TPI to vette motor Part 2
Is my 1990 350 TPI a Direct bolt on to a 1990 vette motor? Is the exhaust ports different because they are aluminum heads? Will my EGR work? Thanks!

Bolt-on, yes; except the center 2 blot holes on each side of the intake will need to be slotted because the 113 casting uses the 86-back bolt angle.
Exhaust, yes.
EGR, no. The 113 casting has no exhaust crossover passage.
